Summary

ZrP2O7 matrix composites reinforced with HVR Nicalon SiC fibers were thermally up shocked to temperatures up to 1400°C. Changes in mechanical (strength and toughness) and electrical (dielectric constant) properties were correlated with microstructural changes. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and x-ray diffraction (XRD) were used to microstructurally characterize the composites. ZrP2O7 composites can withstand thermal up shocking to 1000°C without any strength loss, while at temperatures of 1200°C and above the composite loses strength and toughness.
